BT DLM & sync speeds

An odd one here. Occasionally, I get disconnections on my adsl, probably a few times per week. I'm guessing this behaviour is realtively normal, given the fact that it's a ropey old system that BT use.

Sync speed is around 18mbps with 1mbps up, all was fine and dandy up until recently ... when sync speed was fine and the usual 18mps but noticed that I was getting no more than 1mbps download (upload was unaffected).

Trying all speed test sites, it was apparent there was some issue, onto the BT speedtester, and it said my IP profile was 1250kbps - nowhere near my sync speed. Contacting the ISP, they said that BT's DLM kickingin and that it should up the speed automatically once there's been a good period of around 5 days and that they can only get BT to manually reset it once there has been constant sync of 5 days .

1mbps is pretty pants, and obviously the line isn't really too usable if you try and do many things at once.

Are the sync speeds and ip profile related? If there is sync at xmbps then surely it should be assigning me a profile closer to the sync speed?
It seems a bit crazy for the system to assign a profile that is 1/18th of the sync speed?
And why would it suddenly do it now, when it has been fine for months?

For whatever reason, the upstream test isn't working for me. But here's what's on the screen
